摘要
乐香 2 0 2A是用BAS、黄板所、台九B复合杂交 ,将优良软米性状、香味和早熟显性性状结合在一起 ,再与珍汕 97A杂交并通过连续回交转育而成的优质香软不育系。该不育系表现不育性稳定 ,异交习性好 ,其保持系及所配组合稻米品质优 ,早熟呈不完全显性 ,可恢性好 ,配合力强 ,繁殖制种易获高产 ,2 0 0 1年 8月通过四川省技术鉴定。
Lexiang 202 A is a fine quality CMS line into which the favorable characters of soft grain, aroma and early maturity dominance are incorporated through multiple hybridization of BAS (aromatic), Huangbansuo (soft grain) and Taijiu B (early maturity dominance) and backcrossing to Zhenshan 97A. It has the characteristics of complete and stable male sterility, good outcrossing habits, fine quality, incomplete dominance of early maturity, good restorability, strong combining ability and it is easy to achieve a high yield in its multiplication and hybrid seed production. It was technically identified in Sichuan in August, 2001.
